Code I write over and over for no good reason.
Gonna see what happens by means of accretion.
pip install missingbuiltinsfrom missingbuiltins import jsonl_load, jsonl_dump, chunker
items = chunker(range(5), 2)
jsonl_dump("my_items.jsonl", items) # => 5
got = list(jsonl_load("my_items.jsonl")) # => [[1, 2], [3, 4], [5]]
